| List of Trigonometry Class 11 Formulas |
| sin(−θ)=−sinθ |
| cos(−θ)=cosθ |
| tan(−θ)=−tanθ |
| cosec(−θ)=−cosecθ |
| sec(−θ)=secθ |
| cot(−θ)=−cotθ |
| Product to Sum Formulas |
| sinx siny=12[cos(x–y)−cos(x+y)] |
| cosxcosy=12[cos(x–y)+cos(x+y)] |
| sinxcosy=12[sin(x+y)+sin(x−y)] |
| cosxsiny=12[sin(x+y)–sin(x−y)] |
| Sum to Product Formulas |
| sinx+siny=2sin(x+y2)cos(x−y2) |
| sinx−siny=2cos(x+y2)sin(x−y2) |
| cosx+cosy=2cos(x+y2)cos(x−y2) |
| cosx−cosy=–2sin(x+y2)sin(x−y2) |
Basic Formulas
sin(A+B)=sinAcosB+cosAsinB sin(A−B)=sinAcosB–cosAsinB cos(A+B)=cosAcosB–sinAsinB cos(A–B)=cosAcosB+sinAsinB tan(A+B)=tanA+tanB1–tanAtanB tan(A–B)=tanA–tanB1+tanAtanB cos(A+B)cos(A–B)=cos2A–sin2B=cos2B–sin2A sin(A+B)sin(A–B)=sin2A–sin2B=cos2B–cos2A sin2A=2sinAcosA=2tanA1+tan2A cos2A=cosA–sin2A=1–2sin2A=2cos2A–1=1−tan2A1+tan2A tan2A=2tanA1–tan2APlease excuse me that I couldnt put the divided by lines wherever there is ann empty space assume lines there.
Hope it helped you!
